BUSHING FOR PIANO TUN ING-PIN S.

Speccaton of Letters Patent.

Patented Apr. 30, 1918.

Application filed May 19, 1915. Serial No. 29,122.

To all whom t may concern: l

Be it known that I, HARRY BAYER, a citizen of the United States,residing at Poughkeepsie, in the county of Dutchess and State of NewYork, have invented certain new and useful Improvements in Bushings forPiano Tuning-Pins, of which the following is a specification, referencebeing had therein to the accompanying drawing.

My invention relates to improvement-s in pianos, and more particularlyhas reference to means for securing the piano wires or strings inposition.

Referring to the accompanying drawings, Figure 1 illustrates a brokensection of a portion of a piano embodying an application of myinvention. Fig. 2 is a cross section on the line 2 2 of Fig. 1. Fig. 3is a perspective view of one of my metallic bushings, and Fig. 4 aperspective view of one of the usual form of wooden bushings.

5 indicates the usual iron frame or string plate over which the stringsare secured, and 6 the tuning pins to which the strings are secured. 7indicates the usual wrist plank to which the iron plate 5 is secured andinto which the pins 6 penetrate, said pins being provided with the usualiine thread indicated by the reference character 8. 9 indicates theusual form of wooden bushing shown to better advantage in Fig. 4L whichusually fits into the hole in the iron plate 5 and through which pinssuch as 6 are secured.

It has been found that by forming a metallic bushing such as 10substantially as shown in Fig. 3 with an outer flange or rim such as ll,and by iitting the same within the hole in the iron plate 5 beforeapplying the wooden bushing such as 9 that a better construction isobtained. These metallic bushings are preferably formed out of sheetbrass of such a size that the wooden bushings snugly and tightly littherein and so that the metallic bushings snugly and tightly engage thehole in the iron plate 5. When the pin 6 has been secured therein asshown in Fig. 2 the likelihood of the same coming loose is actuallyreduced to a minimum, and the wooden bushing 9 is better secured inplace. The arrangement also contributes to a more finished appearance asWell asto the quality of the instrument and durability of the same. Thestrings 12 are of course passed through the pins 6 and wound thereuponin the usual manner.

Of course it will be understood that various modifications may be madewithout departing from the spirit of the invention as claimed.

I claim:

1. In combination with the string plate and tuning pins of a piano, abushing through which each pin passes, and a bushing between said firstmentioned bushing and the walls of the hole in said plate within whichsaid bushing is seated.

2. In combination with the string plate and timing pins of a piano, abushing through which each pin passes and a metallic bushing betweensaid first mentioned bushing and the walls of the hole in said platewithin which said metallic bushing is seated, said metallic bushinghaving a flange extending over the edge of the wall in said plate.

3. Bushings for the tuning pins of a piano comprising a straight walledtubular wooden member through'which the pin passes and an outer tubularmetallic member within which said tubular wooden member is seated, saidouter tubular member having an outwardly extending flange. y

In testimony whereof I hereunto affix my signature in the presence oftwo witnesses.
